Environmental Impact of buildings in its Life Cycle evaluation should consider closed-loop systems as represented in Figure 5. In the scheme of Figure 4 are marked in bold the inputs and outputs corresponding just to the use phase in a close loop cycle. When building is designed for deconstruction reuse or refurbishing beyond it s expected lifecycle only these impacts remain present. Materials Local factors Legislation Administration Information - Non toxic - Recycled - Low impact Construction Energy - Renewable sources - Low consumption systems Use Domotics Maintenance Management User Manual Project Refurbishment Recycled materials LCA Energy Natural resources Resources recovery Noise Reduction Renewable energies Water Separative components Fig. 5. Life cycle of buildings in Closed Loop - adapted from Mendonca 2005 307 Deconstruction Roles in the Construction and Demolition Waste Management in Portugal - From Design to Site Management The impacts that building construction has on the environment can be analysed from the following points Position and integration of buildings in the site Influence of design in the Building behavior during its useful life Influence of the equipments in the Building behavior during its useful life Characteristics of the materials used - by the impact that these can produce on the environment during the processes of extraction of raw materials manufacture useful life and in the end of life scenarios reuse recycling energy recovery . 2.1 Energy fluxes of buildings The energy component of the building construction is not only related with the stages of extraction and production of materials and work but continues through the use of the building and even during the demolition so the overall environmental impact assessment of a .
